Expert Solution
Step 1
The devolopment of the male gametophyte or the pollen grains are divided into the two stages,ie microsporogenesis and microgametogenesis. During the microsporogenesis,, archesporial cells within the locules differentiates into microsporocytes or the pollen mother cells capable of undergoing the meiosis to produce the microspores. Pollen mother cells undergo meiosis to produce the tetrad of the microspores(pollen grains).
